A comparison of existing methods of analysis of sensitivity of different parameters in the justification of engineering decisions has been carried out. The  shortcomings of traditional deterministic approaches were identified. A method of gray relational analysis to clarify the degree of feral danger was proposed.  On the basis of the initial data, 22 sensitive sites (flood flow, medium and medium-weighted slope of the basin and the river bed, vegetation) were calculated  with normalized risks, an integrated risk assessment was carried out. The results allowed to refine the previous semi-quantitative risk assessment. The article is  the first to state that that gray relational analysis is universally applicable for analyzing complex systems with multiple criteria in unstable or incomplete data. It  helps to rank alternatives, identify key factors and optimize processes with minimal computational effort. The method is up to date and can be applied in the  variant design of activities for protection against landslides and mudslides, in the assessment of risk of occurrence of dangerous processes.
